Application filed January 31, 1913. Serial No. 745,845.

To all whom it may concern:

Be it known that 1, CHARLES W. GREEN, a citizen of the United States, residing at Cameron, in the county of Steuben and State of New York, have invented new and useful Improvements in Machines for Upsetting Vehicle-Axles, of which the following is a specification.

This invention relates to improvements in machines for upsetting vehicle axles; and it consists of the construction and arrangement of the several parts, as will be hereinafter fully described in this specification and briefly set forth in the claim.

The chief object of the invention is to provide a machine of the type mentioned, which can be simply and cheaply constructed, and, at the same time, be durable and effective in operation.

Other objects of the invention will become apparent upon a complete disclosure thereof.

In the drawing-*Figure 1 is a side elevation of my improved machine; Fig. 2, a top plan view thereof, and Fig. 3, a vertical central longitudinal section of the device.

Referring to the several views of the drawing, the numeral 1 indicates a suitable base, mounted, preferably, upon legs or supports 2, and provided with a central longitudinal groove or channel 2 to facilitate the insertion and removal of the article to be operated upon.

Mounted upon the base is a die-holding guide or box 3 provided at each side with outwardly-extending ears 4:, 4, between which is pivoted, on a shaft 5, a cam-lever (3 provided with a stop 7 for limiting its downward and outward movement, by engaging the end of the base 1.

Pivotally mounted on the base 1 are two oppositely-disposed cam-shaped jaws 8, 8, provided with rearwardly-extending arms or handles 9, 9, the pivotal shafts of the two cam-jaws being yoked together by a bar 10 to prevent undue separation or spreading apart of said cam-shaped jaws 8, 8. The inner face of each cam is provided with vertical serrations or teeth to provide a gripping surface 11, and both cam-shaped jaws are firmly held in gripping position by heavy coil-springs 12, one end of said springs being secured to the camjaws, and the opposite end, preferably, to the die-holding guide or box 3. livoted to the sides of the base, is a bail 13 adapted to open the cam-jaws for the insertion of the axle or other article to be operated upon, and to hold said jaws open until the article has been adjusted to proper position in the machine. blidable in the die-holding guide or box is a suitable upsetting die or former M for receiving the arm of the axle to be upset.

In operation, the axle-arm being properly heated, the camshaped jaws 8, 8, are opened, by swinging the bail 1 3 rearwardly to engage and force inward the arms or handles S), 9, of said cam-jaws S, 8, and the axle inserted between said jaws until the end thereof is received in said die or former, after which the axle is adjusted to proper position to be operated upon, and the said bail turned to its forward position, releasing the arms or handles 9, 5), and allowing the cam-jaws to assume their normal or gripping positions, which they are caused to do by the contraction of the springs which were previously expanded, by the forward inward movement of the cam-arms, to permit the axle to be inserted into said die or former. The axle being firmly gripped between the cam-jaws, the arm-lever (3 is moved in a for ward direction, bringing the cam into contact with the end of the die and forcing it inward on the end of the axle, and thickening the worn portion thereof.

Various details in the construction and arrangement of the several parts of the device may be made without departing from the spirit of my invention or sacrificing the principle thereof.

Having thus fully described my invention, what I claim is 1. A machine for upsetting axles, having in combination a suitable base, a pair of oppositely disposed gripping jaws, pivoted upon said base, means for normally holding said jaws in gripping position, means for opening the jaws, a slidable die mounted upon the base in advance of said jaws, and means for operating said die.

2. A machine for upsetting axles, having in combination a suitable base, a pair of oppositely disposed cam shaped grippingjaws pivoted upon said base, springs for normally holding said jaws in gripping position, means for opening the jaws to allow the work to be inserted therebetween, a dieguide mounted upon the base, a die slidable in said die-guide, and means for operating the die to perform the upsetting operation.

3. A machine for upsetting axles, having in combination a suitable base, a pair of oppositely-disposed gripping-jaws pivoted 7 upon said base, said. ]ELWS being provided With rearwardly-extending arms, springs for normally holding the jaws in gripping position, means adapted to engage said arms to force the jaws apart, a die-guide mounted In testimony whereof I have hereunto set 15 my hand in presence of tWo subscribing Witnesses.
